Clustering Transactions Based on Weighting Maximal Frequent Itemsets
We propose a new similarity measure forcomparing maximal frequent itemset(MFI),whichtakes into account not only non-numeric attributes butalso numeric attributes of each item while computingsimilarity between MFIs.This provides more reliablesoundness for clustering results interpretation.Traditional approaches consider just one side and areapt to lead to unintelligible clustering results fordecision-makers.Based on properties of maximalfrequent itemset(MFI),we construct a multi-levelhierarchical model(MHM)for our clusteringalgorithm.Moreover,to evaluate our approach andcompare with other similarity strategies,we constructan original evaluating strategy NF_Measure whichintegrates both quantity similarity and qualifysimilarity between transactions.We experimentallyevaluate the proposed approach and demonstrate thatour algorithm is promising and effective.
